Basic bangla sign language recognition and sentence building using Microsoft Kinect
MetadataShow full item record
How do a deaf of mute people communicate with each other? Or, even bigger question, how do they make other people understand their messages? The answer is, Sign Language. It is not that easy, most people do not know sign languages. To improve that situation, there have been many researches going on to translate sign language into spoken language. The main purpose of our thesis was to build a system similar to that in Bangla language. When one signs a language, he mostly uses his hands and head. The facial impression is also important. In our system, we tracked the skeleton with the help of Kinect. The system performs hand segmentation, finger identification and the number of fingers the signer has used using K-curvature algorithm while making the gesture. To determine the movement, the information about the skeleton joints is checked from the data set for each gesture. Finally the system shows the output for which the conditions are matched. Thus, the system recognizes the sign language gestures. Keywords: Bangla Sign Language, Kinect, Skeleton Tracking, Finger Identification, Kcurvature algorithm.
